The single-event radiation hardened ISL7124SRH, ISL7124SEH consist of four independent, high gain, internally frequency compensated operational amplifiers, specifically designed to operate from a single power supply over a wide range of voltages. These devices are functionally equivalent to industry standard 124 types, offering improvements in supply current and power supply rejection ratio. Constructed with Intersil's dielectrically isolated, radiation hardened silicon gate (RSG) BiCMOS process, these devices are immune to single event latchup. Additionally, the design has been hardened to prevent single event transients (SETs) in excess of 1V for LETs up to 36MeV/mg/cm2. The ISL7124SRH, ISL7124SEH have been specifically designed and manufactured to provide highly reliable performance in harsh radiation environments. They are total dose hardened to 300krad(Si) and offer guaranteed performance over the full -55°C to +125°C military temperature range. Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-02542.
